I don't have access to Solaris box right now so I don't know if this solution is very reliable:
This will put number of gigabytes of RAM into "mem" variable.
That's nice and clean, but I don't know if this will work on all systems of this type. I'll have to try this on similar boxes in our other data centers.
Hi
is there a cmd in hpux 11 to determine the physical size of the hard disk.
not bdf command.
i have searched the other threads here but cant find an answer.
thank you guys (4 Replies)
Hi All,
I am trying to find the physical memory usage by each process/users.
Can you please let me know how to get the memory usage?.
Thanks,

I'm writing a shell script to display as much useful information on physical and virtual memory availability and usage as possible. I need a CLI tool to print these numbers for me.
The utilities that I know to give out some statistics are the following:

vmstat

This is the report I got running the comand rptconf, but I would like to know what is the capacity of the disks installed into our server power 6 with AIX

Hi,
I have a server (BL460c) with 32G of physical RAM.
It currently only uses approx 5% its capacity but will use more (not sure how much more) pending the launch of further applications.
If I need to build another node of similar functionality should I consider downgrading the physical... (2 Replies)
Hi,
kstat -p -m zfs -n arcstats -s size returns
zfs:0:arcstats:size 8177310584
this values is approx (7.61 GB)
but my Physical Memory size is only 6144 Megabytes.
Can this happen ?
if yes, then how can I find free memory on the system.
BTW, I ran the kstat commands from a Non... (2 Replies)
Hi, looking to upgrade memory on a pair of T5220's from 32GB to 64GB. Cannot determine current DIMM size and slots used. i.e. not sure if Qty 16 x 2GB or Qty 8 x 4GB. If there are no empty slots, i need to go with higher density DIMMs and retire exsisting the 2GB prtdiag follows.

have been trying to create a 2 GB ramdisk (virtual) to run on my T-2000 simulator (Legion) which has sun4v architecture. I have a SPARC workstation which runs on sun4u architecture with Solaris 10.
I have created a ramdisk image using dd command, newfs, then used ufsrestore to restore the... (3 Replies)

mem
MEM(4) Linux Programmer's Manual MEM(4)NAME
mem, kmem, port - system memory, kernel memory and system ports
DESCRIPTION
/dev/mem is a character device file that is an image of the main memory of the computer. It may be used, for example, to examine (and even
patch) the system.
Byte addresses in /dev/mem are interpreted as physical memory addresses. References to nonexistent locations cause errors to be returned.
Examining and patching is likely to lead to unexpected results when read-only or write-only bits are present.
Since Linux 2.6.26, and depending on the architecture, the CONFIG_STRICT_DEVMEM kernel configuration option limits the areas which can be
accessed through this file. For example: on x86, RAM access is not allowed but accessing memory-mapped PCI regions is.
It is typically created by:
mknod -m 660 /dev/mem c 1 1
chown root:kmem /dev/mem
The file /dev/kmem is the same as /dev/mem, except that the kernel virtual memory rather than physical memory is accessed. Since Linux
2.6.26, this file is available only if the CONFIG_DEVKMEM kernel configuration option is enabled.
It is typically created by:
mknod -m 640 /dev/kmem c 1 2
chown root:kmem /dev/kmem
/dev/port is similar to /dev/mem, but the I/O ports are accessed.
It is typically created by:
mknod -m 660 /dev/port c 1 4
chown root:kmem /dev/port
